.To all whom it maj/concern: i i

vBe it known that I, 'HENRY B. KIPE'R,

a citizen of the United States, residingat Lancaster, inthe county of Lancaster and State of Pennsylvania, have inventedlcertain new and useful Improvements in Cream- Separatore; `and I do hereby declarethe'following to bealfull, clear,and eXact descrip,- tion of thev invention, such as will-enable others skilled in the `artto whichfit appertains to make andv usethe name. l

This invention relates to centrifugal liquid separators, and 'more particularly lto centrifugal machines especially designedfand A" l lightcreammayjbeobtained, or'any desired adapted to separate cream from `milk` and which are known in the art as cream sepa.

rators. l l

The primary object ory my invention is to provide simple and efficient means forregu# `lating the relative proportions of .milk and cream so that the percentage of cream may be varied at will, andthe separation -ei'ected in such manner that k'the cream discharge maybe gradually lessened while the quantity of milk is gradually increased, orvice versa, thereby enabling the user to 4obtain .either a 'very light or thin cream and comparatively llittle skimmedmillno'r avery thick or heavy cream andl more skimmed milk, or to separate the .milkf and cream in whatever proportionsth'e'l user `may desire, and'to maintain auniform admixture of milk and ycream when a thickfor heavy cream is not desired. n

The vinvention consists essentially in improved means 'forl regulating the i relative proportions of thejseparated liquid or milk and cream, including'a regulating screw or equivalent 'device' located Hat the upperV end milkv of thez'separator bowl and having a exit or passage therethrough in communica:-

tion with the space from which the skimmed milk 's discharged, whereby the percentage of milk and cream may be variedto such an'. extent that either very heavy or very quality oradmixture between the two eX'- 't'remes,' `by simply adjusting the screw or regulating' device Vcontrolling the milk ekitl The yinvention will first be hereinafter more particularly described,` with reference tothe accompanying drawings,'fwhich form a vpartof'y this specification, and. then j pointed vout iin' the claims at the end of the description- Inl said drawings, Figure'l represents a vertical section, partly 'in side elevation, of
